Three methods of dating rocks
There are three main assumptions that must be made to accept radiometric dating methods.These must be accepted on faith in uniformitarian and naturalistic frameworks.Relative ages are assigned to rocks based on the idea that rock layers lower in the strata were deposited before rock layers that are higher.Creationists do not necessarily disagree with this concept, but it can only be applied to layers that are found in one location and/or can be determined to have been deposited in a continuous layer over a very wide area.

The starting isotope is called the parent and the end-product is called the daughter.
The time it takes for one half of the parent atoms to decay to the daughter atoms is called the half-life.
Uniformitarian geologists use so-called dating methods to determine the ages of the surrounding rocks.
Certain types of rocks, especially those that form from magma (igneous), contain radioactive isotopes of different elements.
Most scientists and many Christians believe that the radiometric dating methods prove that the earth is 4.5 billion years old.
